As the inventive concept allows for various changes and numerous embodiments, particular embodiments will be illustrated in the drawings and described in detail in the written description. However, this is not intended to limit the present invention to specific embodiments, it should be understood to include all changes, equivalents, and substitutes included in the spirit and scope of the present invention. In describing the drawings, similar reference numerals are used for similar elements.

Terms such as first and second may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be referred to as the second component, and similarly, the second component may also be referred to as the first component. The term and / or includes a combination of a plurality of related items or any item of a plurality of related items.

When a component is referred to as being "connected" or "connected" to another component, it may be directly connected to or connected to that other component, but it may be understood that other components may exist in the middle. Should be. On the other hand, when a component is referred to as being "directly connected" or "directly connected" to another component, it should be understood that there is no other component in between.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting of the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, the terms "comprise" or "have" are intended to indicate that there is a feature, number, step, operation, component, part, or combination thereof described in the specification, and one or more other features. It is to be understood that the present invention does not exclude the possibility of the presence or the addition of numbers, steps, operations, components, components, or a combination thereof.

Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the present invention. Hereinafter, the same reference numerals are used for the same components in the drawings, and redundant description of the same components is omitted.

The present invention relates to a method, an apparatus, and a system for capturing data of a graphics device interface (GDI), which is printing data of a point of sales (POS) application. The present invention discloses a method for increasing the tax rate for cash payments by sniffing data generated by GDI when a store clerk prints a receipt using a POS application.

The three main components involved in the general document printing process of the first terminal are the application, the GDI, and the spooler.

The application may be a POS application installed in the first terminal. When there is a print command for a document that the application is reading / editing, the application creates a print job of the document by calling GDI. If the application is a POS application, the print command may relate to a cash receipt or a credit card receipt. (S110)

GDI is a Microsoft Windows-like operating system that draws all graphical objects, including common elements that draw scroll bars and lines on the screen. The application in use sends a parameter to the GDI for the image to be displayed, which generates the image by sending the command to an imager (eg, monitor, printer) or other device. The present invention stores and extracts data generated by GDI in a separate memory during a series of normal image generation. If the application is a POS application, and the application commands printing a cash receipt, GDI generates image data for outputting the cash receipt. The image data is stored and secured in a separate memory or the like.

Meanwhile, according to an operating system of the first terminal, a process of performing a print command of a user may be changed. For example, when the operating system of the first terminal is Windows Vista, the print job generated by the application may call WPF (Windows Presentation Foundation) instead of GDI. Also, if Apple's Mac OS is adopted, GDI can be replaced by QuickDraw or Quartz. (S120)

GDI also translates the application's print request into a Device Driver Interface call. If the output format is an Extended Meta File (EMF), GDI spools to an SPL file. Also, when spooled in RAW format, GDI is called directly into the printer graphics DLL. After this, the rendered data is passed to the spooler. This is again passed through a language monitor DLL, a port monitor DLL, and the like (not shown). The printer driver is responsible for converting the printer's DDI calls into printer commands to be sent to the printer device.

In addition, the spooler is a main component of the printing interface of the first terminal, and may be installed in the first terminal in the form of an executable file managing the printing process. When the application creates a printer device context (DC) in response to a user's print command, the spooler may determine the location of the required printer driver and load the printer driver. The type of data recording the print job can also be determined by the spooler.

The GDI data extracted in the above step is output to the outside through the communication unit of the first terminal. The communication unit of the first terminal may be a UBS interface, but is not limited thereto. When the first terminal outputs image data to the outside, data for identifying the first terminal may be output together.

Image data and identification data transmitted to the second terminal are transmitted to an external server. In this case, the identification data of the second terminal may be transmitted to the external server instead of the identification data of the first terminal.

For example, the first terminal may be a personal computer in a store where a POS application is installed, and the second terminal may be a device including a communication unit for transmitting GDI data generated from the POS application to an external server. In this case, since the second terminal is smaller in size and lower in production cost than the first terminal, the IRS can easily supply the second terminal to each store instead of the first terminal. In other words, the Internal Revenue Service may supply a second terminal capable of generating identification data for recognizing each store to each store. The second terminal spread as described above may combine the identification data generated through the second terminal with the GDI data received from the first terminal and transmit the combined data to the IRS server. The identification data and the GDI data may be combined to be generated as one data. In this case, the identification data may be generated at the front or rear of the GDI data frame, so that no error occurs in the information such as sales and sales time included in the GDI data. Can be coupled to a specific location.

As another example, the identification data may be a first terminal unique device number which is a unique identification number of the first terminal, a POS application unique identification number, a business registration number of a store where the first terminal is installed, and the like. Based on the identification data, the server can determine from where the GDI data is received. For example, when the application is a POS application and the identification data is a business registration number, the server receiving the identification data and the GDI data may know how much cash receipts have been issued in which stores.

Of course, the present invention is not limited to transmitting the image data and the identification data to the server through the second terminal after transmitting to the outside through the communication unit of the first terminal, as in this embodiment, through the communication unit of the first terminal You can also send directly to the server. In this case, the first terminal may include a communication unit capable of wired and wireless communication with the server. For example, data may be transmitted and received through an antenna according to a WiBro or WiMax communication method, which is a wireless Internet communication module, or a GSM, GPRS, CDMA, WCDMA, HSDPA, HSUPA, or HSPA communication method, which is a wireless mobile communication module. have. In addition, of course, the data can be delivered to the server through the general wire communication.

First, when the second terminal connects to the first terminal, a program capable of copying image data generated by the GDI and storing it in a predetermined memory is automatically installed in the first terminal. The second terminal according to the present embodiment may include a module for automatically installing a program and a memory storing the program. When the second terminal is connected to a specific host on which the POS application as the first terminal is installed, the module is automatically executed to install the program in the first terminal.

More specifically, a module for automatically installing a program (which may correspond to the program automatic installation unit of FIG. 4) automatically executes the second terminal when the second terminal is first connected to a specific host terminal such as the first terminal. Recognize it as a device. Next, when the second terminal is recognized as an automatic execution device, a program capable of copying image data generated by the GDI stored in the memory of the second terminal and storing it in a predetermined memory is automatically installed in the first terminal. Of course, it can be installed by manual operation according to the user's choice. For example, a module for automatically installing a program of the second terminal may recognize the second terminal as the same as a CD device that is automatically executed, and install the program.

In more detail, the second terminal is recognized as an automatic execution device upon first access to the UBS interface of the first terminal, and the second terminal is subjected to automatic execution by a UBS hub controller (not shown). The program stored in the memory is automatically installed in the first terminal. In this case, the first terminal allows a program stored in a memory of the first terminal to be installed at a predetermined position by a host controller (not shown). A module for automatically installing a program of the second terminal is a processor that provides a series of instructions and is composed of hardware such as a semiconductor chip. It is preferable to configure the hardware of the semiconductor chip in this way, because the hardware is safe from intrusion by a virus or the like.

On the other hand, according to another embodiment of the present invention, when the second terminal is reconnected to the first terminal, it is possible to copy the image data generated by the GDI to the signal from the first terminal that has already installed a program that can store the predetermined data in a predetermined memory. Accordingly, the operation of the module that automatically installs the program of the second terminal can be blocked. This blocking can reduce the loss of program reinstallation.

On the other hand, in another embodiment of the present invention, the second terminal does not need to store in the memory a program for capturing GDI image data to be used in the first terminal, and the website address and login of the service provider that provides the program. You can store only the information you need. In the present embodiment, a nonvolatile memory such as a flash memory, an EEPROM, an EPROM, or the like may be used, and may be configured as a small EEPROM of about 100kb. According to the present embodiment, the size of the memory used in the second terminal can be reduced, and since the GDI image data capture program installed in the first terminal is provided from the service provider's server through the second terminal, The GDI image data capture program can be installed in the first terminal. In addition, since it is only necessary to access a website of a service provider provided by the second terminal without physically introducing a second terminal to install the program on the first terminal, it is also effective for the maintenance of the program.

Through the program installed through the above steps, the data requested for printing by the POS application is captured and transmitted to the second terminal, and transmitted again to the server through the second terminal. (S230)

Finally, the data requested by the POS application is printed on paper through the image forming apparatus physically connected to the second terminal. Of course, the image forming apparatus need not necessarily be connected to the second terminal, but may be connected to the first terminal.

The method invention of the present invention described above may be implemented in computer-readable code / instructions / program. That is, a first step of a Windows application requesting an output through an image forming apparatus to a Windows-based operating system; And a program for executing a second step of storing image data generated by a graphics device interface (GDI) or a Windows Presentation Foundation (WFP) in a memory in response to the output request of the first step. Is illustrated.

For example, it may be implemented in a general-purpose digital computer for operating the code / instructions / program using a computer-readable recording medium. The computer-readable recording medium may be a magnetic storage medium (eg, ROM, floppy disk, hard disk, magnetic tape, etc.), optical reading medium (eg, CD-ROM, DVD, etc.) and carrier wave (eg Storage media, such as through the Internet). In addition, embodiments of the present invention may be implemented as media (s) containing computer readable code, such that a plurality of computer systems connected through a network may be distributed and processed. Functional programs, codes and code segments for realizing the present invention can be easily inferred by programmers in the art to which the present invention belongs.

Hereinafter, an electronic calculator for extracting printing data of a Windows application according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a block diagram illustrating a first terminal 100 in which a program for extracting GDI image data is installed, according to an exemplary embodiment. The foregoing description of the server transmission method of the GDI image data has been omitted as much as possible.

The first terminal 100 mainly includes an application 110, an image data extraction unit 120, a GDI 130, a printer driver 140, a spooler 150, a first memory 160, and a USB interface 170. Include in the configuration.

The application may be a POS application installed in the first terminal. For example, the user may press a print button such as a receipt using a POS application installed in the first terminal.

GDI draws all graphic objects, including common elements that draw scroll bars and lines on the screen, and image data to be output through the image forming apparatus when a printing command such as a cash receipt is transmitted from a POS application or the like. Create

The image data extraction unit extracts data and stores it in a predetermined memory before the image data generated by the GDI is accumulated in the spooler. GDI spools to different types of files depending on the type of extended meta file (eg EMF, RAW) of the output format. Therefore, the image data extraction unit extracts data before the data generated by the GDI is stacked in the spooler in different forms depending on the type of printer or extended meta file. In this way, image data can be secured in a fixed form with respect to the output regardless of the execution environment such as a printer or an extended meta file.

The printer driver converts the image data generated from the GDI or XPS into a printer command to be sent to the printer device. More specifically, the printer driver converts the printing conditions and the print data provided from the GDI into a printer language that can be interpreted by the image forming apparatus. The printer language is instructions sent to an image forming apparatus by a first terminal, such as a personal computer, to indicate how to construct a printed document, which manages font size, graphics, compression of data, color, and the like. .

The spooler spools the print data converted into the printer language in the print driver, and provides the spooled print data to the port monitor (not shown) in accordance with the processing speed of the image forming apparatus.

The first memory serves to store the image data extracted from the image data extraction unit.

The USB interface serves to connect with an image forming apparatus or a communication apparatus capable of transmitting image data to an external server. The UBS interface is not limited to one and may have many.

As another embodiment of the present invention, the first terminal of FIG. 3 may further include a communication unit capable of communicating with another terminal such as an external server. The communication unit does not cover wired and wireless.

4 is a diagram illustrating a configuration of a second terminal 200 according to an embodiment of the present invention.

The second terminal is connected to the first terminal in which the POS application is installed, and may include a program automatic installation unit 210, a second memory 220, a communication unit 230, and a USB interface 240.

When the second terminal is electrically connected to the first terminal, the program automatic installation unit automatically installs a program for storing GDI image data in the first terminal in the first terminal.

The second memory serves to store a program to be installed in the first terminal, and the communication unit communicates with other terminals except for the first terminal. The USB interface serves as a channel for electrically connecting with the first terminal. The USB interface is not limited to one and can be many.

As another embodiment of the present invention, an image forming apparatus may be connected to the second terminal. In more detail, the second terminal transmits the GDI image data transmitted from the first terminal to the external server through the communication unit, and the spooled data through the printer driver is bypassed to the image forming apparatus to the paper from the image forming apparatus. Let it print

That is, when the second terminal receives predetermined data from the first terminal, the control unit (not shown) included in the second terminal filters the data, and transmits the GDI data to the outside through the communication unit, and other data. Passes to image shape device via USB interface.

As another embodiment of the present invention, the control unit (not shown) of the second terminal, when the data is transmitted to the external server through the communication unit, it is possible to include and transmit the data that can identify the second terminal together. have. The unique data for identifying the second terminal may be provided through an IC card (eg, a subscriber identification module (SIM)) that implements a subscriber identification module inserted into a slot (not shown) of the second terminal.

If a business establishment that is newly issued with a business number and starts a business already has a first terminal and a second terminal in which a POS application is installed, the Internal Revenue Service may only issue an IC card that can identify the business place. In this way, the IRS can prevent the waste of administrative power to disseminate the second terminal and to install a program for capturing image data of the GDI on the first terminal.

5A through 5C are diagrams illustrating a system for extracting printing data of a Windows application according to an embodiment of the present invention. The foregoing description of the server transmission method, the first terminal and the second terminal of the GDI image data is omitted as much as possible.

The system of FIG. 5A may be composed of a first terminal 100, a second terminal 200, a printer 300, and a server 400.

When the second terminal is connected to the first terminal, the program automatic installation unit of the second terminal automatically installs the GDI image data capture program stored in the memory in the first terminal. Then, when the output request from the POS application, the image data extraction unit captures the image data generated by the GDI and transmits it to the second terminal, the second terminal transfers the data to the server through a communication unit installed separately from the outside, The printing data is transferred to a printer which is an image forming apparatus for output.

FIG. 5B is another embodiment of the present invention. Unlike FIG. 5A, the second terminal is configured to include a communication unit. As illustrated, the controller of the second terminal filters the data received from the first terminal into data to be transmitted to the server and data to be transmitted to the printer. FIG. 5C is a system configuration diagram illustrating each configuration of the system of FIG. 5A in more detail.

Referring to FIG. 6, first, a second terminal (hereinafter referred to as U-port in the present embodiment) in which a program capable of GDI sniffing is stored is a UBS port in the first terminal (hereinafter referred to as POS host in this embodiment). Connected via

POS Host is a system that combines the functions of cash registers and computer terminals, which are commonly used in general stores such as restaurants and shops, to not only settle the sales amount but also collect and process various information and data necessary for retail management. Point of sale management system. The POS host related application may be an application for Windows installed on a Windows-based operating system.

When the U-port is connected to the POS host, the U-port is recognized as an autorun device, and a program that can sniff the GDI stored in the U-port's memory is automatically installed on the POS host. In addition to the installation automatically, the installation can be performed manually by a user operation.

Then, when the customer in the store pays cash to purchase goods or services, the manager of the store uses the POS host to issue a cash receipt in paper form as evidence of the cash payment.

More specifically, when the POS application of the POS host requests receipt printing, the POS application is a Windows application, and thus generates data using GDI for printing. After that, the generated GDI data is stored in the spool, and the data stored in the spool is transferred to the printer under the control of the CPU of the host and printed on the actual paper.

According to the present invention, in order to extract GDI data, a program capable of sniffing GDI stores GDI data generated by a POS application in a separate memory and outputs the data to U-port. The output method to U-port does not cover wired or wireless. Also, depending on the operating system, XPS data may be sniffed instead of GDI data.

Thereafter, the U-port combines the received GDI data and data for identifying a store that issued a cash receipt (hereinafter referred to as store identification data in this embodiment). The data that identifies the store that issued the cash receipt is the unique ID code of the POS host, the code assigned when the GDI sniffing program is installed on the POS host, the U-port unique ID code, or the S-port to be mentioned later. It may be a unique identification code. In order to transmit the GDI data to the IRS server without error, the store identification data may be combined at a predetermined position such as the front or rear of the GDI data.

Thereafter, the combined GDI data and the store identification data are transmitted to the IRS server through a communication unit included in the U-port. The communication unit for communication with the IRS server may be provided as a separate terminal (hereinafter referred to as S-port in this embodiment) separated from the U-port. The transmission method with the IRS server does not select wired or wireless.

The IRS server can secure accurate transaction basis data for transactions settled in cash through the analysis of the received data, and the IRS can make the tax base for the transactions.

In addition, the U-port is also connected to the printer, the printer outputs a cash receipt as usual, the output cash receipt is delivered to the customer. The process of outputting the cash receipt is the same as a general printing process, and the U-port functions to bypass the data received from the spool in the host as it is to the printer.

Although described with reference to the embodiments, it will be understood by those skilled in the art that the present invention may be variously modified and changed without departing from the spirit and scope of the invention as set forth in the claims below. Could be.
